Description
Technical field
The utility model relates to a kind of power transformer, relates in particular to a kind of power transformer for soft switch welding machine.
Background technology
Along with the IGBT soft switch technique is more and more ripe, frequency is more and more higher, power is increasing, now be widely used in the inversion welding source, but the copper loss of main transformer, iron loss, manufacture craft all can not have very big breakthrough all the time, directly have influence on performance, technology and the cost of welding machine.Conventional power transformer volume is big, the number of turn is many (primary and secondary), manufacture craft bothers, loss is big, the cost height.As depicted in figs. 1 and 2, existing power transformer comprises transformer core 1, is wound with primary and secondary coil 2 on the described transformer core 1, and described primary and secondary coil 2 leads to binding post 3 respectively, and wherein primary coil is greatly about 37 circles; Secondary coil is in parallel about 5 circles and the many groups of need greatly.Such structure, the copper loss of main transformer, iron loss are still bigger, must air blast cooling.The manufacture craft difficulty is bigger in addition, and cost also is subjected to the restriction of material high always.Therefore, be necessary to provide a kind of power transformer for soft switch welding machine, to reduce copper loss, the iron loss of main transformer, promote technological level and reduce cost.
The utility model content
Technical problem to be solved in the utility model provides a kind of power transformer for soft switch welding machine, can reduce copper loss, the iron loss of main transformer, and simplified structure also reduces cost.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of power transformer for soft switch welding machine, comprise transformer core, be wound with the primary and secondary coil on the described transformer core, described primary and secondary coil leads to binding post respectively, wherein, described transformer core is FERRITE CORE, and the number of turn of secondary coil is 1 in the described primary and secondary coil, and the number of turn of primary coil is 6～10 in the described primary and secondary coil.
The above-mentioned power transformer that is used for soft switch welding machine, wherein, described transformer core is 2 pairs of EE-110 FERRITE CORE that are oppositely arranged.
The above-mentioned power transformer that is used for soft switch welding machine, wherein, the nominal operation frequency of described power transformer is 40KHZ, and rated current is 400A, and the number of turn of primary coil is 8 in the described primary and secondary coil.
The utility model contrast prior art has following beneficial effect: the power transformer that is used for soft switch welding machine that the utility model provides, adopt FERRITE CORE to replace iron core commonly used, suitably increase cross section of transformer core, reduce primary and secondary coil turn to greatest extent, making the transformer secondary output coil is 1 circle, determine number of primary turns according to the power output size again, copper loss, the iron loss of main transformer obviously reduce, efficient improves, reduce copper loss, the iron loss of main transformer, simplified structure also reduces cost.
Description of drawings
Fig. 1 is the existing power transformer structural representation that is used for welding machine;
Fig. 2 is to view along A among Fig. 1;
Fig. 3 is used for the power transformer structural representation of soft switch welding machine for the utility model.
Among the figure:
1 transformer core, 2 primary and secondary coils, 3 binding posts
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 3 is used for the power transformer structural representation of soft switch welding machine for the utility model.
See also Fig. 3, the power transformer that is used for soft switch welding machine that the utility model provides comprises transformer core 1, be wound with primary and secondary coil 2 on the described transformer core 1, described primary and secondary coil 2 leads to binding post 3 respectively, wherein, described transformer core 1 is FERRITE CORE, and the number of turn of secondary coil is 1 in the described primary and secondary coil 2, and the number of turn of primary coil is 6～10 in the described primary and secondary coil 2.
The power transformer that is used for soft switch welding machine that the utility model provides, wherein, described transformer core 1 is preferably 2 pairs of EE-110 FERRITE CORE that are oppositely arranged, and high frequency performance is good, and is cheap.Suitably increase cross section of transformer core, reduce primary and secondary coil turn to greatest extent, making the transformer secondary output coil is 1 circle, determines number of primary turns according to the power output size again.Be 40KHZ for the nominal operation frequency for example, rated current is the power transformer of 400A, and the number of turn of primary coil is 8 can satisfy the power current requirements in the general described primary and secondary coil 2, and copper loss, the iron loss of main transformer obviously reduce, efficient improves, and reduces the manufacture craft difficulty.
Though the utility model discloses as above with preferred embodiment; so it is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection range of the present utility model is worked as with being as the criterion that claims were defined.
